Although lands owned by educational institutions were at first exempted from nationalization, other sources of support, such as impropriated tithes and standard donations from chapters and monasteries, dried up.

Tithes, destined for the upkeep of the parish clergy but often impropriated by monasteries or laymen, took around another 8 per cent on average.

Many tithes had been commuted to cash payments or impropriated by others who then paid the vicar an annual salary.
